Release Date: August 12, 2025
Host: Aruna Masinha, Global Economist at Morgan Stanley
Duration: Approximately 4 minutes and 42 seconds

In the episode titled "The Credibility of Inflation Targets," Aruna Masinha delves into the critical role that inflation targets set by central banks play in shaping market behavior and economic activity. The discussion navigates through the complexities of maintaining inflation expectations, the challenges faced by different economies, and the broader implications for major central banks like the Federal Reserve (Fed).

Introduction: The Importance of Inflation Targets

Aruna Masinha opens the discussion by emphasizing the centrality of inflation targets in current financial market debates, especially in the context of tariff-driven inflation. She states:

“Tariff driven inflation is at the center of financial market debates right now.” (00:30)

Masinha underscores the conventional wisdom that central banks should tolerate one-off price surges “if inflation expectations are anchored low enough.” This premise sets the stage for a broader exploration of how inflation targets, expectations, and central bank credibility intertwine.

The Fed’s Experience with Inflation Targeting

Masinha critically examines the Federal Reserve’s (Fed) approach to inflation during and post-COVID-19 pandemic. She highlights that the Fed initially posited COVID-induced inflation as “transitory,” a stance heavily reliant on the assumption that “anchored inflation expectations would pull inflation down.” However, after experiencing four years of inflation rates exceeding their targets, the Fed has adopted a more cautious outlook.

“The Fed is more cautious now. After four years of above target inflation.” (01:10)

This shift raises pertinent questions about the effectiveness of merely announcing inflation targets without achieving the corresponding credibility and expectation management.

South Africa Reserve Bank (SARB) as a Real-Time Experiment

The South Africa Reserve Bank (SARB) serves as a focal case study for understanding the practical challenges of inflation targeting. Initially, SARB set its inflation target within a range of 3% to 6% with plans to transition to a narrower 2% to 4% range over time. Recently, SARB de facto shifted its target to the lower end at 3%, pending formalization by the Ministry of Finance.

“But the SARB has succeeded in pulling inflation down. It has established credibility.” (01:50)

Despite these achievements, Masinha points out that fully anchoring inflation expectations at the new target remains a work in progress. She identifies external factors such as fiscal policies and exchange rate volatility as significant hurdles:

“The central bank cannot control all the drivers of inflation in the short run. For South Africa, fiscal targets and exchange rate movements are prime examples.” (02:30)

Lessons from Brazil: A Historical Perspective

Drawing parallels, Masinha examines Brazil’s experience with inflation targeting. After abandoning its currency peg in 1999, Brazil’s Central Bank (BCB) set an initial inflation target of 8%, which was progressively lowered to 4.5% in 2005 and further to 3% by 2024.

“Fiscal outcomes, market expectations and currency volatility have been hard to contain.” (03:00)

Brazil’s journey illustrates that successful inflation targeting demands more than just numerical targets; it requires robust institutional frameworks and sustained political consensus to manage both internal and external economic pressures.

Implications for the Federal Reserve and Global Economies

Masinha extrapolates the lessons from South Africa and Brazil to offer insights for the Fed and other global economies. She argues that “simply announcing an inflation target likely does not solve the problem.” The Fed’s prolonged period of above-target inflation underscores the necessity of demonstrating credibility through consistent policy actions rather than declarations alone.

“Our read of the evidence is that inflation expectations and central bank credibility come from hitting the target, not from announcing it.” (04:20)

She also touches upon uncertainties lingering from COVID-19-induced inflation and the potential exacerbating effects of ongoing tariff measures, suggesting that these factors could further complicate the path to achieving and maintaining target inflation rates.

Conclusion: Building Credibility Through Consistent Policy

In concluding the episode, Masinha emphasizes that the credibility of inflation targets is built through consistent achievement of those targets rather than their mere announcement. For emerging markets like South Africa, maintaining higher real interest rates and ensuring alignment between monetary and fiscal policies are crucial steps toward stabilizing inflation expectations.

“While we ultimately expect the SARB to be able to anchor inflation expectations, the journey may not be a quick one.” (04:00)

Masinha's analysis provides a nuanced understanding of the delicate balance central banks must maintain to achieve economic stability, highlighting that credibility is earned through persistent and credible policy measures.
